Abstract (en)
A method is disclosed for determining a local hot gas temperature in a hot gas duct downstream a combustion device. The method comprises extracting at least one flue gas sample at at least one specific cross-sectional location of the hot gas duct downstream the combustion device, determining at least one flue gas species concentration in the sample, and determining the local flue gas total temperature based upon the at least one flue gas species concentration. In an embodiment, the method is conducted at the entry to an expansion turbine of a gas turbine engine. At least one vane member is provided in the guide vane row which comprises an airfoil (10), wherein at least one sample extraction orifice (13, 14, 15, 16, 17) is provided on an outer surface of the airfoil, and a sample duct (131, 141, 151, 161, 171) is provided in fluid communication with the sample extraction orifice and running inside the airfoil. The flue gas samples are extracted through the sample extraction orifices.
